Abstract
The utility model discloses a kind of water centrifugal pump leakproof axle sleeve, annular groove is arranged in the close seam crossing with the contact jaw of sleeve nut in axle sleeve, is sealing ring in annular groove.The water centrifugal pump leakproof axle sleeve of the utility model, transformation is low with maintenance cost, greatly improves work efficiency, reduces the repair rate of pump, effectively prevents liquid medium and leaks along the seam of sleeve nut and axle sleeve, is conducive to wide popularization and application.
Description
Technical field
The utility model relates to field of mechanical technique more particularly to a kind of water centrifugal pump leakproof axle sleeves.
Background technique
The evaporating, emitting, dripping or leaking of liquid or gas of horizontal double water uptaking centrifugal pumps is concentrated mainly at the sealing of spindle nose, and sealing mostly uses material filling type close
Envelope.It checks in maintenance repair and is leaked at the airtight and watertight padding of spindle nose, analysis finds that the aqueous medium of leakage is along in axle sleeve
Wall flows to the seam outflow of warp beam sleeve nut at filler, and then it is outer to leak to pump.With the daily anxiety of the energy, the energy of each company
The needs of energy loss caused by the phenomenon that increasingly reinforcing of management, water centrifugal pump evaporating, emitting, dripping or leaking of liquid or gas firmly prevent, to water centrifugal pump
There are demands for improvement.
Therefore, those skilled in the art is dedicated to developing a kind of water centrifugal pump leakproof axle sleeve, it is intended to solve the prior art
Dielectric leakage problem in middle water centrifugal pump use process.
Utility model content
In view of the drawbacks described above of the prior art, technical problem to be solved in the utility model be in the prior art, water from
In heart pump use process, liquid medium is along water centrifugal pump sleeve lining to pump external leakage, and liquid medium is along sleeve nut and axle sleeve
Seam leakage the problem of.
To achieve the above object, the utility model provides a kind of water centrifugal pump leakproof axle sleeve, the axle sleeve it is close with
Annular groove is arranged in the seam crossing of the contact jaw of sleeve nut, is sealing ring in the annular groove；
Further, the sealing ring is closing " O " type sealing ring；
Further, the sealing ring material is rubber material；
Further, on the annular groove location processing rib that the end face of circular hole and sleeve nut has a common boundary in axle sleeve；
Using above scheme, water centrifugal pump leakproof axle sleeve disclosed by the utility model is had following technical effect that
1, the water centrifugal pump leakproof axle sleeve of the utility model, using connecing for the close and sleeve nut in water centrifugal pump axle sleeve
Annular groove is arranged in the seam crossing of contravention, and annular groove location is processed on the rib that the end face of circular hole and sleeve nut has a common boundary in axle sleeve,
The sealing to form both direction is squeezed through sleeve nut after placing sealing ring in annular groove, effectively prevents liquid medium along axle sleeve
The leakage of the seam of nut and axle sleeve, eliminates liquid medium and leaks at stuffing-box along sleeve lining, prevented evaporating, emitting, dripping or leaking of liquid or gas
Phenomenon reduces the maintenance down rate of water centrifugal pump, extends the service life of pump, energy saving, reduces costs；
2, the water centrifugal pump leakproof axle sleeve of the utility model, is not required to additionally purchase axle sleeve, can be in existing water centrifugal pump axle sleeve
On processed, it is fast and convenient, it is durable, transformation it is low with maintenance cost, greatly improve work efficiency, reduce the inspection of pump
Frequency repair rate, is conducive to wide popularization and application；
In conclusion the water centrifugal pump leakproof axle sleeve of the utility model, transformation is low with maintenance cost, substantially increases work
Efficiency reduces the repair rate of pump, effectively prevents liquid medium and leaks along the seam of sleeve nut and axle sleeve, is conducive to wide
General popularization and application.
The technology of the design of the utility model, specific structure and generation is imitated below with reference to attached drawing and specific embodiment
Fruit is described further, to be fully understood from the purpose of this utility model, feature and effect.
Detailed description of the invention
Fig. 1 is the utility model water centrifugal pump leakproof axle sleeve structure diagrammatic cross-section；
Fig. 2 is the diagrammatic cross-section that the utility model water centrifugal pump leakproof axle sleeve is assemblied in water centrifugal pump；
In figure, 1, pump case；2, impeller；3, axle sleeve；4, gland；5, sleeve nut；6, pump shaft；7, sealing ring；8, key
Slot；9, annular groove.
Specific embodiment
Introduce preferred embodiments of the present invention below with reference to Figure of description, keep its technology contents more clear and
It is easy to understand.The utility model can be emerged from by many various forms of embodiments, the protection of the utility model
Range is not limited only to the embodiment mentioned in text.
In the accompanying drawings, the identical component of structure is indicated with same numbers label, everywhere the similar component of structure or function with
Like numeral label indicates.The size and thickness of each component shown in the drawings are to be arbitrarily shown, and the utility model is not
Limit the size and thickness of each component.Apparent in order to make to illustrate, some places suitably exaggerate the thickness of component in attached drawing.
As illustrated in fig. 1 and 2, the utility model water centrifugal pump leakproof axle sleeve, the close and sleeve nut 5 of the axle sleeve 3
Annular groove 9 is arranged in the seam crossing of contact jaw, and 9 position of annular groove is that processing end face of circular hole and sleeve nut 5 in axle sleeve 3 has a common boundary
Rib on；It is closing " O " type rubber seal 7 in annular groove 9；
The water centrifugal pump leakproof axle sleeve of the utility model is assemblied in water centrifugal pump, as shown in Fig. 2, 1 is pump case, 2 pump leaves
Wheel, 3 be the axle sleeve of the utility model, and 4 be gland, and 5 be sleeve nut, and 6 be the pump shaft of water centrifugal pump, and 7 be to be placed in ring
The sealing ring of shape slot, 8 be the keyway of water centrifugal pump, and 9 be axle sleeve 3 and the seam processing sets up of the contact jaw of sleeve nut 5
Annular groove；
It is worked using the water centrifugal pump for the water centrifugal pump leakproof axle sleeve for being assembled with present embodiment, assembles rear axle lantern ring
Shape slot and slot inner seal ring warp beam sleeve nut squeeze the sealing to form both direction, use by long-time, do not occur liquid
Medium does not occur the liquid medium edge of water centrifugal pump along the seam of sleeve nut and axle sleeve and along the leakage of sleeve nut screw thread
The situation that water centrifugal pump sleeve lining is corroded to pump external leakage and pump shaft and axle sleeve.
The preferable specific embodiment of the utility model is described in detail above.It should be appreciated that the ordinary skill of this field
It according to the present utility model can conceive without creative work and make many modifications and variations.Therefore, all the art
Middle technical staff passes through logical analysis, reasoning, or a limited experiment according to the design of the utility model on the basis of existing technology
Available technical solution, all should be within the scope of protection determined by the claims.
